Public bug reported:

Router RA rule is added to compute node to allow VM to accept RA from
router interface on network node. However, this is only added when
router port which sends RA is created before VM port is created.

We should add trigger to allow RA from router port when router port is
created after VM port is created.


Looking at the code, we can change notify_security_groups_member_updated in securitygroups_rpc_base.py from

        if port['device_owner'] == q_const.DEVICE_OWNER_DHCP:
            self.notifier.security_groups_provider_updated(context)
        else:
            self.notifier.security_groups_member_updated(
                context, port.get(ext_sg.SECURITYGROUPS))

To:

        if port['device_owner'] in [q_const.DEVICE_OWNER_DHCP, 
                                                         q_const.DEVICE_OWNER_ROUTER_INTF]:
            self.notifier.security_groups_provider_updated(context)
        else:
            self.notifier.security_groups_member_updated(
                context, port.get(ext_sg.SECURITYGROUPS))

To get provider rule update triggered when route port is created.
